The First Avengers: Age of Ultron Trailer is the Most Revealing "Teaser" I've Ever Seen

Grab the popcorn -- the first Avengers: Age of Ultron trailer is here. I can't believe they're calling this a "teaser" -- unless the final movie clocks in at about five hours long, this is one of the most action-packed teaser trailers ever.

Another ensemble piece set in Marvel's comic book universe, it sees Hulk, Iron-Man, Thor, Captain America, Hawkeye and Black Widow teaming up once again to take on a new robotic foe, the titular Ultron. Played by James Spader (well, voiced at least, or that's one hell of a robot suit) Ultron is the work of the-Icarus like Iron Man alter-ego Tony Stark,who created the artificial intelligence as a peace-keeping force, which inevitably turns on the humans it was designed to protect.

As well as plenty of Hulk-smashing, keep an eye out for Aaron Taylor Johnson's Quicksilver (the second casting of the role in as many years after Evan Peter's show-stealing scene in X-Men: Days of Future Past), Elizabeth Olsen as the Scarlett Witch and Gollum himself, Andy Serkis, in an as-yet-unclear role. Ulysses Klaw, perhaps? Which would also suggest Marvel is finally getting around to doing a Black Panther movie too...[Marvel]
